The Dr. we are consulting wants to change the suger pill for insulin. He explained to us that sugar pill only works for so long. I am starting him on insuline, my question is? Would the insuline help him with his kidney condition, should I be worried about his kidneys- Right now he has swollen feet and ankles, and cramps on his legs and a rash in his back. Concerned wife.

Dear Jacky
i can understand your concern
i am very sorry about the condition of your husband
in my opinion considering the change from oral pills to insulin is the best advice given by your doctor
At the level of creatinine more than 1.6mg/dl we need to stop metformin and should consider taking insulin for control of blood sugar as at that level of renal damage metformin will be more harmful.
insulin helps in recovery of kidney to certain extent.
the reason for hyperkalemia is due to decreased kidney function.
i suggest you to use leached vegetables and meet your nephrologist to prescribe this kind of potassium binding resins.
swollen feet might be due to water retention due to reduced kidney function
he will be alright in no time
